  • Archaeology (7.74%)
  • Diamond (6.07%)

What are the most cited papers published in the journal?

  • Inclusions in Diamond (262 citations)
  • Inclusions in Diamonds (79 citations)
  • Colour centres in diamond (72 citations)

Research areas of the most cited articles at The Journal of Gemmology:

The published articles focus on Natural (archaeology), Geochemistry, Optoelectronics, Diamond and Analytical chemistry. The most cited articles with studies in Geochemistry featured incorporate elements of Corundum, Mineral and Vanadium. Research in Diamond discussed in the most cited publications is concerned with the study of Metallurgy as a whole.

What topics the last edition of the journal is best known for?

  • Optics
  • Mineral
  • Archaeology

The previous edition focused in particular on these issues:

The Journal of Gemmology was organized to reinforce research efforts on Diamond, Archaeology, Geochemistry, Metallurgy and Nuclear chemistry. The Diamond study featured in The Journal of Gemmology draws parallels with the field of Engineering physics. The work tackled in the journal goes beyond the discipline of Archaeology as it also encompasses Emerald.

The Journal of Gemmology focuses on Geochemistry as well as the interrelated topic of Quartz.

The most cited articles from the last journal are:

  • Platinum Jewellery Business Review 2021 (0 citations)
  • SSEF’s ‘Understanding Gemstones’ Courses (0 citations)
  • Natural Diamond Price Guidance (0 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

The top authors publishing in The Journal of Gemmology (based on the number of publications) are:

  • Karl Schmetzer (88 papers) published 1 paper at the last edition the same number as at the previous edition,
  • Carol M. Stockton (85 papers) published 28 papers at the last edition, 3 less than at the previous edition,
  • Brendan M. Laurs (40 papers) published 4 papers at the last edition, 6 less than at the previous edition,
  • R. Keith Mitchell (38 papers) absent at the last edition,
  • Henry A. Hänni (29 papers) published 1 paper at the last edition.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The top affiliations publishing in The Journal of Gemmology (based on the number of publications) are:

  • Utrecht University (1 papers) absent at the last edition,
  • King's College London (1 papers) absent at the last edition,
  • Anton de Kom University of Suriname (1 papers) absent at the last edition.

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 98.78% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 100.00% were posted by at least one author from the top 10 institutions publishing in the journal. Another 0.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 0.00% of all publications and 0.00% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
